how to add prefix 00 for Cisco ATA186 ?

I need to add 00 to all the number i dial out from ata186. how can i do that ?

i delete everything in dialplan and put Pn00t4 there, doesn't work.

The 'P' rule is a separate rule that is in addition to the rest of your dial plan.

You would probably want to change the default dial plan to something like this:

Pn00|*St4-|#St4-|911|1>#t8.r9t2-|0>#t811.rat4-|^1t4>#.-

This worked for me (Version 3.02.01(050616A)). Check the 186's call history to verify.

great. it works

another question :

how to remove 00 or 011 prefix for ata186 and sipura? for example, if dial 00125478931.. or 011125478931..

125478931.. will be sent out.

Use the 'R' rule which is the enhanced prefix rule. It will match entire strings instead of just matching a digit. The - (dash) removes digits based on the subrule.

R--([0-9]-)
This would remove the first two dialed digits as long as they match the part in parentheses (the last dash is a wild card).

So you would want two 'R' rules. First one to match wins.
R--(00-)|R---(011-)

You can also have it replace a portion with another like so:
R--99(00-)
which if the dialed string started with 00 would remove the first two digits and prepend 99 to the dialed string.
